Above; the push rod 9 is staggered from the through hole 4 ; the push rod 9 is fixedly connected with the soft film 3 ; the filter chamber 10 is provided with a push rod 9 whose pushing direction is toward the soft film 3 .

The first conduit 6 and the second conduit 7 are inserted into the bladder, and the flushing fluid flows from the flushing chamber 11 to the first conduit 6 to enter the bladder for flushing. After flushing, the flushing fluid carries the flushing material through the second conduit 7 and flows into the filtering bottle 1. Chamber 10; the filter chamber 10 is provided with a push rod 9 passing through the rinse bottle 1, the push rod 9 pushes the direction towards the soft film 3, the push rod 9 is connected with the soft film 3, pushes the push rod 9, and the push rod 9 pushes the soft film 3 Squeeze to the side wall of the flushing bottle 1, in the flushing chamber 11, the soft membrane 3 squeezes the flushing fluid to flow into the first catheter 6 and into the bladder for flushing; pull the push rod 9 in the reverse direction, the soft membrane 3 is also gradually reset, flushing The liquid carries the rinse back to the rinse bottle 1 from the second conduit 7, the rinse falls on the filter screen 8, and the rinse liquid flows into the filter chamber 10 and enters the circulation.

When the washing liquid in the filter chamber 10 is more than the washing chamber 11, the washing liquid will flow from the filter chamber 10 to the washing chamber 11, the movable baffle 5 will open the through hole 4 with the flow of the washing liquid, and the washing liquid can pass through the The hole 4 flows into the flushing chamber 11; when the flushing liquid in the flushing chamber 11 is more than the filtering chamber 10, the flushing liquid will tend to flow from the flushing chamber 11 to the filtering chamber 10. The baffle 5 will close the through hole 4 with the flow of the washing liquid, and the washing liquid cannot flow into the filter chamber 10 through the through hole 4 .

One end of the annular wall 15 is flush with the bottle cap 2. When the rinse liquid enters the rinse bottle 1 from the bottle cap 2, cover the bottle cap 2 tightly.

The arrangement of the annular wall 15 makes the inner cavity 142 in a sealed state during the use of the flushing device, ensuring that the inner cavity 142 and the outer cavity 141 are used in the flushing device. No communication during the process, the flushing fluid will not flow between the inner cavity 142 and the outer cavity 141, preventing the flushing fluid from the outer cavity 141 into the first catheter 6 to bring the flushing material left in the inner cavity 142 back to the bladder.

The soft film 3 is provided with a through hole 4, and the position where the push rod 9 is in contact with the soft film 3 is staggered from the position of the through hole 4 to ensure that the push rod 9 can push the soft film 3 to squeeze the flushing liquid in the flushing chamber 11, preventing the The push rod 9 is pushed into the through hole 4, so that the flushing liquid flows back from the flushing chamber 11 to the filter chamber 10, the flushing liquid cannot enter the upper flow chamber 14 from the flushing chamber 11, and the device cannot be used; the soft membrane 3 has elasticity.

The push rod 9 is fixedly connected with the soft film 3 , and when the push rod 9 is reversely pulled, the soft film 3 can be quickly reset.

The above are only the preferred embodiments of the present invention, of course, the scope of the rights of the present invention cannot be limited by this. Several improvements and changes are made, and these improvements and changes are also regarded as the protection scope of the present invention.
